SPECIFICATION forming part of Letters PatentNO. 755,401, dated March 22,1904. Appleman med January 21,1903. Renewed August 31, 1901i. serial No.171,454. (No man.)

Beit known that I, J osErH K. SHARPE, J r.,

a citizen ofthe United States, residing at Indianapolis, in the countyof Marion and StateV ofiIndiana, have invented certain new and usefulImprovements in Ceiit-rltugalElevators, of which the following 1s aspecification.

My present invention relates'to elevators 2o be first fullyA describedand then pointed out in the claims.

which are made a part hereof, and on which similar `reference charactersindicate similar parts, Figure 1 is a side elevation of athreshlng-machine or separator equipped with one ofmy improvedelevators; .Fig-2,11 top or'v plan view showing ,the saidA elevator andthe adjacent portions of the separator; Fig. 3, a

jacent parts on a considerably-enlarged scale as seen when looking inthe direction indicated by the arrows from' dotted lines 3 3 in Figs.4 1,and 4, andFig. 4 a longitudinal vertical sectional view thereof as seenwhenlooking in the direction indicated bythe arrows from thedotted lines4 4 in Figs. 2 and 3.

' have E'shown a complete separator v21, in-

cluding also partof a Wind-stacker, for the purpose of illustrating therelative position thereto of the elevator'embodying my invention -whenthe same is attached tothe separator and readyfor'operation. It willofcourse, however, be understood that my improved elevator may be usedwith other forms of separator without departing from myinvention,theform 'shown beingmerely for purposes of Referring to the accompanyingdrawings,

transverse vertical sectional view through the elevator boot or housingand immediately ad! .ingto said inlet, a duct, preferably composed Voftwo sections 33and 34a-anda suitablesepaf illustration. There are,however, certain advantages in using this invention where a windstackeris employed greater than where other stackers are employed, as willappear hereinafter,'and I have chosen to illustrateso much ot' awind-stacker as makes this clear and have illustrated so much oftheparticular form of wind-'stacker which'I prefer as is necessary forthe purpose. In this-form of 'wind-stacker the stacker-fan Ais mountedon the shaft 23 and is driven b v a belt 24 from the separator-cylindershaft 25, and the blast from'said fan is delivered into the base orstraw-chamber portion 26 of said stacker and drives the-straw frontisaid chamber into and'through the straw carrier trunk or duct, of whichonly a fragment 27 is shown, Y 1

f The elevator comprises a housing 3 1', having an inlet in one side toadmit the grain, a throwing-wheel 32, contained in said housing andhaving an opening in one side correspondratingfhead, and these (in use)arerigidly secured to the separator-frame by various supporting slingsand 'braces 36, a bracket 37 and stays 38 and 39, asshown, these beingVvaried 'in size, form, and arrangement according to.- the separator'towhich theelevator is attached. The throwing-wheelis similar in forni,arrangement, and operation' tothat shown and described in the Schumanpatent, No. 603, 925, dated May 10, 1898, and in construction to thatillustrated vin the Schuman patent, No. 641,045,l January 9,` 1900, -orNo.' 646,877, dated April 3, 1900, and therefore need not befurther'described'herein. .85 The bearing 41, in which the shaft 42 ofsaid throwing-wheel is mounted, 'is the `,same as that which forms thesubject-matter of the Williamsonpatent; No. 663,372, dated. N ovember 7,1899. Said throwing-wheel is prefv erably driven by a belt 43,,ru'nnngto'a pulley 44 'on' the shaft 42 .from a pulley 45onaco'unter-shaft 46, and Vsaid counter-shaftis driven, preferably; byabelt 47, running toa-pulley 48 thereon from 'a pulley onthecylinder-shaft 25 ofthe separator. f It will Vbe seen that-I 'am airwhich may be carried with i' grainv will fall to the bottom height tosecure and assignment.

'matter of a companion enabled by this provision of a counter-shaft tovary the speed of the thrwing-wheel 32 as may be desired by simplyvarying the sizes of the pulleys 45 and 48.

The duct, as above stated, consists of two duct-sections33 an`d34, thelower one of which extends within the other. This enables them to beadjusted in relation to eachother so as to vary the length of the duct,and thus permit the elevator to be conveniently attached to differentsizes and makes of separators. It likewise permits the separatingdieadto be` adjusted to a higher or lower level, according to the work to bedone. The lower duct-section 33 has a vent at 30 of .similar characterand purpose to that which forms the subjectu matter. of the Patent No.619,844, granted to The Pneumatic Elevator andMTcigher Company, February21, 1899, upon my application 35 forms the subjectapplication dated andfiled concurrently herewith, and. therefore will not be furtherdescribed herein.

In operation the grain as it is threshed cornes from the separatorthrough the graindelivery spout thereof, which is commonly either whatis known as a shakespout or an spout. In Fig. 3 1 have, shown a fragment51 of an auger-spout containing an auger 52 of a usual form. Aninlet-spout 53 runsfrom this graindelivery spout into the eye of -thchousing 3l of the elevator and carries the grain to the center of thethrowingJwheel 32, which impels it by centrifugal force through the ductcomposed` of the duct-sections 33 and 34 into the 'separating-head 35,from which any the grain will escape through the top ofl saidseparating- The separatinghead head,(which is reticulated or perforated,being commonly composed of woven wire,) while the of said head' and bedelivered through its` mouth either to the weighr-dru'm 61 or toanyother spout or receptacle which may be provided. For .the purpose ofillustrating a complete machine 1 have-'shown 4a weigher similar to thatVforming the subject-,matter of the Schuman patent, No. 650,593, andabaggersinjilar'to'that shown in t-h ;1Schuman patent'io.l 623,109.

In my elevator there 'are no,.changes of direction in the duct-pipe,andgthegrain is consequentlythro-wn directly from lthe housing totheseparating-head, `which takes le'sspower thanfany arrangexrient whe-reinchanges f direction are embodied. The duct runs at an angle from theplace where the grain is'received fup to a" st fiicicnt -the desireddelivery therefrom and also suicicntly tojthe rear so` that machine. AInan'ar'rangement like that illusbe taken tot `wagon o'n the ground :itcan v of the separator withstanding' on either side u auge!" grain isbeing bagged l out'changing the position of the elevator or bagger. theseparator as the elevator, the sacks can be placed therein from wherethey sit, While in case the wagon is on the other side ofthe l separatorthe operative merely has Vto step across behind the separator from oneside to the other to deliver the sackspthereto. All devices in the arethus generally dispensed with. Having thus fully described my saidinvention, what I claim as new, and desire to secure by Letters Patent,is-

1. The combination, with a threshing-mag chine, of a housing securedthereto opposite the grain-delivery spout and having a central` openingin the side nearest the threshing-machine, a grain-throwing wheelmounted in said housing also having a central openingin its side nearestthe th reshing-machine adapted Ato receive the grain as it comes fromsaid grain-delivery spout in through the housingV opening and' to actasa centrifugal grain-impelling device, a 4duct .leading from the neckof said housing in an inclined direction to the desired point ofdischarge, a separating-head l on the end of said pipe, and adischarge-outlet on the under side of said separating-head', l wherebythe grain is thrown in a direct line I from the throwing-wheel to thepoint of separation and thence discharged in one -direction while theair and dust are dischargedin another direction.

2. The combination, inan elevator, of a' I housing, athrowing-wheeltliereimaductleading directly from the dlscharge-opemng otthe If the wagon is on the same side of nature i of cross-conveyershousing to the required point of delivery and provided with a venten itsouter or under tions adjustable one upon y the other, and aseparating-head connected to the outer end of said duct and adapted todischarge the grain in'one direction andl permit the air to' escape inanother direction, substantially as set forth.

3. The combination in an elevator, of a housing having amaterial-receiving opening 'responding' opening registering.therewith,a
